Hello guys,
Here I am with another interesting article in the category Today in History on the one and only Ophthalmologist who has been awarded Nobel prize for Ophthalmology related research. Hope you have guessed it by now.

Yes, It’s Allvar Gullstrand and it’s his birthday. A Swedish Ophthalmologist and a self-taught mathematician. Slit-lamp invented by him is the most common inventions of him which every student must have known by now. When I sat down to write this article, I have found tons of information online. So, I will just try to make things as simple as possible.
